IWAMA project consortium

IWAMA project started back in March 2016 – with ambitious goals and results we wanted to achieve to improve the state of the Baltic Sea. After three intensive years of joint implementation of activities in ten countries, testing and learning from each other, we are extremely happy and proud to share a wide collection of produced outputs with our colleagues in the region. Equipped with strong partnership enthusiastic to bring the change to their workplace and the region; with a steadily expanding pool of external stakeholders closely involved in cooperation we are ready to overcome water challenges across the borders.

Pilot investment: Advanced control in Grevesmuhlen wastewater treatment plant

Project activities related to Grevesmühlen WWTP have been carried out by two project partners: with the investment hosted by the plant, a decision making tool for optimized process operation and mass flow management has been prepared by the aqua & waste International GmbH company. To calibrate the developed tool, Grevesmühlen WWTP launched investigation of the process under varying conditions, focusing particularly on thermal hydrolysis.

Pilot investment: Reject-water treatment system in Tartu wastewater treatment plant

Tartu Waterworks Company is the second biggest municipal wastewater treatment plant in Estonia and one of the many WWTPs in the Baltic Sea Region where anaerobic digestion of sludge is applied. There, a full-scale deammonification technology was developed and installed with regard to demonstrate in-situ start-up of deammonification without external seed.

Pilot investment: Energy-efficient sludge drying in Jurmala wastewater treatment plant

Within the framework of IWAMA project Jurmala WWTP is piloting a drying and incineration unit (hereafter, unit). The unit is designed to reduce the amount of surplus sludge from the wastewater treatment process using vapor of thermal decomposition of volatile products and non-condensable gases as fuel. It is integrated into the existing technological chain of WWTP.

Pilot investment: Combined anammox-constructed wetland pilot-plant in Gdansk wastewater treatment plant

Investment in Gdansk aims to develop and test energy efficient and cost-effective concept uniting processes that require low energy consumption treatment. The investment includes a combined anammox-constructed wetland pilot plant and additional energy meters installed at the WWTP. The examined technology focuses on minimizing energy consumption for the removal of organics and nutrients while maximizing recovery of organic matter from wastewater to produce renewable energy.

Pilot investment: Energy optimized control of large wastewater treatment plant in Kaunas

The pilot investment involves installing the online nitrogen measurement devices to be used for monitoring nitrogen concentration in the aeration tanks, as well as installing the mass airflow sensors to measure air flow to the aeration tanks to allow advanced process automatization and programming for energy optimization of the blowers.

Pilot investment in Kaunas

Pilot investment on the Kaunas wastewater treatment plant is one of the largest in the IWAMA project. Installations on the plant have been ongoing since summer 2017, and will continue next year. We introduce you to the concept of the energy optimized control system constructed on Kaunas WWTP to support the smart energy management and reduction of nutrients.
